Product details
Overview
TMS320F28035PAGQ from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated Control Law Accelerator (CLA), 64KB flash, 10KB SARAM, 14-channel 12-bit ADC (4.6 MSPS), 14 ePWM channels, and automotive-grade AEC-Q100 qualification (–40°C to 125°C). It targets high-precision motor control in EV charging power modules and solar string inverters.
For engineers reviewing the TMS320F28035PAGQ datasheet, TMS320F28035PAGQ pinout, TMS320F28035PAGQ application, or TMS320F28035PAGQ equivalent, key selection criteria include CLA-accelerated closed-loop timing, HRPWM dual-edge modulation capability, on-chip comparator routing to PWM, and AEC-Q100 temperature compliance for automotive power electronics.
Technical Context
The TMS320F28035PAGQ implements a Harvard-architecture C28x CPU with atomic instructions and zero-wait-state memory access, enabling deterministic 16.67 ns cycle-time execution. Its CLA operates independently of the main CPU using 32-bit floating-point math, offloading PID and observer computations from real-time control loops.
Peripheral integration includes ePWM modules with high-resolution extensions (HRPWM) supporting frequency-modulated dual-edge control, analog comparators with internal 10-bit references directly modulating PWM outputs, and a 12-bit ADC with 216.67 ns conversion time and ratio-metric VREFHI/VREFLO support - all optimized for fast current/voltage feedback in digital power converters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28035PN | 80-pin LQFP package; adds 16 GPIO, 2 additional eCAP inputs, and 1 extra eQEP module | Better suited for complex motion control with multi-axis encoder feedback and expanded I/O | Select when board layout allows larger footprint and additional peripherals are required |
| TMS320F28034PAG | Same 64-pin TQFP package but with 32KB flash, 8KB SARAM, and no CLA accelerator | Limited to simpler control tasks where floating-point acceleration is not needed | Select for cost-sensitive non-automotive applications with lower firmware complexity |
Compared with TMS320F28035PN, the TMS320F28035PAGQ offers identical core performance and CLA capability in a smaller 64-pin footprint but trades 16 GPIO and one eQEP for AEC-Q100 qualification - making it optimal for space-constrained automotive power modules where functional safety and thermal robustness are prioritized over I/O count.

Does the TMS320F28035PAGQ include a hardware floating-point unit (FPU)?
No, the TMS320F28035PAGQ does not include a hardware FPU. It uses a fixed-point C28x CPU core. However, it integrates a dedicated Control Law Accelerator (CLA) that executes 32-bit floating-point math independently of the CPU - providing FPU-like computational capability for control law execution without impacting main CPU bandwidth.
How many ePWM channels does the TMS320F28035PAGQ support, and how many have high-resolution capability?
The TMS320F28035PAGQ supports 14 ePWM channels total, with 7 of them featuring High-Resolution PWM (HRPWM) capability. These HRPWM channels provide dual-edge modulation with sub-nanosecond resolution, enabling precise timing control for SiC and GaN gate drivers in high-frequency resonant converters.
Is the TMS320F28035PAGQ pin-compatible with other devices in the F2803x family?
Yes, the TMS320F28035PAGQ shares the same 64-pin TQFP (PAG) footprint and pinout with other PAG-packaged F2803x variants including TMS320F28030PAG through TMS320F28034PAG. Signal assignments, power/ground locations, and JTAG interface pins are identical - enabling hardware reuse across performance tiers within the same package option.
What analog peripherals are integrated into the TMS320F28035PAGQ?
The TMS320F28035PAGQ integrates a 12-bit, 4.6 MSPS ADC with 16 input channels and dual sample-and-hold; three analog comparators with internal 10-bit DAC references; an on-chip temperature sensor; and ratio-metric VREFHI/VREFLO support - all accessible via shared AIO/GPIO pins and directly routable to ePWM trip zones for fast protection response.
